EC3278-2.4A/32V Syn. Rectified Step-Down Converter

EC3278-2.4A/32V Syn. Rectified Step-Down Converter
General description
The EC3278 is a monolithic synchronous buck regulator.The device integrates two 90mΩ MOSFETs, and provides 2.4A of continuous load current over a wide input voltage of 4.75V to 32V.Current mode control provides fast transient response and cycle-by-cycle current limit.An adjustable soft-start prevents inrush current at turn-on,and in shutdown mode the supply current drops to 1µA.This device, available in an SOP-8(Exposed PAD)package, provides a very compact solution with minimal external components.

Features
• 2.4A Output Current
• Wide 4.75V to 32V Operating Input Range
• Integrated 90mΩ Power MOSFET Switches
• Output Adjustable from 0.923V to 30V
• Up to 93% Efficiency
• Programmable Soft-Start
• Stable with Low ESR Ceramic Output Capacitors
• Fixed 200KHz Frequency
• Cycle-by-Cycle Over Current Protection
• Input Under Voltage Lockout

Applications
• Distributed Power Systems
• Networking Systems
• FPGA, DSP, ASIC Power Supplies
• Green Electronics/ Appliances
• Notebook Computers
